[Bug] Printing donation with Product Drive but no Product Drive Participant gives unhandled exception

[cielf]

Summary

If you print a donation with a product drive, but no product drive participant, it gives an unhandled exception. It should skip trying to print the product drive participant instead.

Why?

We've got over 3000 of this case in production -- so this is definitely a normal business case.

Details

To replicate

sign in as org_Admin1@example.com
Click Donations
New Donation
enter a donation that has a product drive, but leave the product drive participant blank
save
print
It gives a 500 error

What should happen instead

It looks like this is happening when the "Donation from" section is being printed. If it's a product drive, but without a product drive participant, put "Product Drive -- [the name of the product drive]" there instead.

Hint:

donation_pdf.rb has a class called DonorInfo you should look at.

#Criteria for completion

• behaviour as described above
• tests to support the behaviour

Hi, I would like to work on this as my first contribution to this repo. Thanks to the helpful Getting Started docs and the very detailed write up for this issue, I think I have been able to reproduce it locally:
